TraPc Sign Assist
Function of TraPc Sign Assist
TraPc Sign Assist detects traPc signs with the
multifunction camera (  page 211). It assists
you by displaying detected speed limits and over- taking restrictions in the Instrument Display.
Observe the notes on driving systems and yourresponsibility; you may otherwise fail to recognize
dangers (  page 211).
Since TraPc Sign Assist also uses the data stored
in the navigation system, it can update the display in the following situations without detecting traPc
signs.
The camera also detects traPc signs with a
restriction indicated by an additional sign (e.g.
when wet). These are displayed only if a restric-
tion applies or if the system cannot clearly deter-
mine whether the restriction applies.
Warning when the maximum permissible speed is
exceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. To do
this, you can specify in the multimedia system by how much the maximum permissible speed can
be exceeded before a warning is issued. You canspecify whether the warning is to be just a visualwarning or an acoustic one as well.

\f symbol next to a traPc sign in the Instru-
ment Display indicates that additional traPc
signs have been detected. These can also bedisplayed in the media display and optionally in the head-up display.
If TraPc Sign Assist cannot determine the maxi-
mum permissible speed (e.g. due to missing
signs), the following display appears in the Instru- ment Display:
This is displayed continuously if the vehicle is in a
country where TraPc Sign Assist is not supported.
TraPc Sign Assist is not available in all countries.
\bAlso observe the information on display mes-
sages in TraPc Sign Assist (  page 427).

actual driving situation.
Driving and parking241

Keep the actual traPc situation con-
stantly in view when approaching a traf-
fic light and when changing lanes.Avoid looking at the Instrument Display and Head-up Display for a long time.
The Instrument Display and Head-up Display (if
available) show the traPc light icon and remaining
time until the next green phase as a countdown.
Example representation in the Instrument Display
1TraPc light icon and countdown of remaining
time until the next green phase timeThe display is hidden about Nve seconds before
the traPc lights change to green.\bThe display also goes out in the following
cases:
= When turning oM before the intersection
into a cross or side street
= When turning before the intersection\bThe direction arrows are displayed depending
on the following functions:
= A turn signal is set
= A lane is recommended during active
route guidance
If neither function is active, the remaining time until the next green phase for the lane
straight ahead is displayed.\bUse of the traPc light information service
requires the regular transmission of vehicle
positions and driving directions to Mercedes-
Benz. The data is immediately anonymized by Mercedes-Benz and forwarded to the providerof the traPc light information service. The
vehicle positions and driving directions aredeleted aser a very short time (a few sec-
onds) and are not permanently saved.
If you do not want to transmit the vehicle
positions and driving directions, you have the following options:
= You deactivate the service in the
Mercedes me portal.
= You have the service deactivated at an
authorized Mercedes-Benz Center.
= You deactivate the service in the Assis-
tance menu in the multimedia system
(  page 243).\bThis traPc light information service is only
available in certain cities and regions.
The function is supported under the following con-
ditions:
= The vehicle is equipped with a multimedia sys-
tem featuring navigation and a communication
module with an activated, integrated SIM card.
= You have a user account for the Mercedes me
Portal.
= The vehicle has been connected with the user
account.
242Driving and parking

=The navigation services option is available,
subscribed to and activated in the Mercedesme Portal.
= The traPc light data service belongs to the
scope of the navigation services.
The current vehicle position and the direction of
travel are transmitted via the communication module and aligned with the data from the traPc
light data service provider. The provider gathers data from traPc lights which transmit their chang-
ing phases. When the vehicle approaches an inter- section with networked traPc lights, data is trans-
mitted to the vehicle.
A set turn signal les or right and lane recommen-
dations during active route guidance are taken
into account for the display.
The service is for information purposes only and is
not linked to any other vehicle functions, systems or components. Please note that the displayed data is not available in all traPc areas and may be
incorrect.
Certain light signal systems automatically adapt
their switching times to the current traPc situa-tion. This can lead to a sudden change in the
countdown display.
The information in the Instrument Display is shown aser selecting the display contents in the
Assistance menu. If another menu is selected, the
traPc light countdown is not displayed.
Also observe the following information:
= select a speed adapted to the traPc, sur-
roundings and weather conditions
= Observe actual traPc signs
= Observe applicable traPc rules and regula-
tions
Please observe the notes on driving systems and your responsibility. You could otherwise fail to rec-
ognize dangers.
System limits
The display does not appear in the following situa-
tions, for example:
= There is no traPc light data available.
= The time remaining until the next green phase
is less than ten seconds.= Emergency vehicles or local public transport
are located in the vicinity of the intersection.
= The data transmission from the vehicle has
been interrupted.
= The traPc light systems are located in a con-
struction site area or are undergoing mainte-
nance.
= The light signal system is malfunctioning.

Blind Spot Assist and Active Blind Spot Assist withexit warning
Function of Blind Spot Assist and Active BlindSpot Assist with exit warning
Blind Spot Assist and Active Blind Spot Assist use two lateral, rear-facing radar sensors to monitorthe area up to 130 s (40 m) behind and 10 s
(3 m) next to your vehicle.
If a vehicle is detected at speeds above approx-
imately 8 mph (12 km/h) and this vehicle subse- quently enters the monitoring range directly next
to your vehicle, the warning lamp in the outside
mirror lights up red.
Permanent status display in the instrument clus- ter:
= ¸ (gray): system is activated but inopera-
tive
= ¸ (green): system is activated and opera-
tional
If a vehicle is detected close to your vehicle and
you switch on the turn signal indicator in the cor- responding direction, a double warning tone
sounds and the red warning lamp in the outside
mirror Oashes. If the turn signal indicator remains
switched on, all other detected vehicles are indi- cated only by the Oashing of the red warning
lamp.
If you overtake a vehicle quickly, no warning is given.&WARNING Risk of accident despite Active
Blind Spot Assist
Active Blind Spot Assist does not react to the
following:
= if you overtake a vehicle too closely so that
it is in the blind spot area
= if vehicles traveling at a much faster speed
approach and then overtake
Active Blind Spot Assist may not give warnings
or intervene in such situations.
Always pay careful attention to the traPc
situation and maintain a safe distance at
the side of the vehicle.Observe the notes on driving systems and your responsibility; you may otherwise fail to recognizedangers (  page 211).
Exit warning
The exit warning is an additional function of Blind Spot Assist and can warn vehicle occupants about approaching vehicles when leaving the vehicle
when stationary.&WARNING Risk of accident despite exit
warning
The exit warning neither reacts to stationary
objects nor to persons or road users approaching you at a greatly diMering speed.
The exit warning cannot warn drivers in these situations.
Always pay particular attention to thetraPc situation when opening the doors
and make sure there is suPcient clear-
ance.
If there is a vehicle in the monitoring range, this is
indicated in the outside mirror. If a vehicle occu-
pant opens the door on the side with the warning,
244Driving and parking

a warning tone sounds and the warning lamp in
the outside mirror starts to Oash.
This additional function is only available when
Blind Spot Assist is active. When the exit warning
is activated, it can warn vehicle occupants for up to three minutes aser switching the vehicle oM.
The exit warning is no longer available once the warning lamp in the outside mirror Oashes three
times.
The exit warning is only an aid and not a substi-
tute for the attention of vehicle occupants. The responsibility for opening and closing the doorsand for leaving the vehicle remains with the vehi- cle occupants.
System limits
Blind Spot Assist and Active Blind Spot Assist may be limited in the following situations, in particular:
= if there is dirt on the sensors or the sensors
are obscured
= in poor visibility, e.g. due to fog, heavy rain or
snow
= if there are narrow vehicles, e.g. bicycles or
motorbikes= if the road has very wide or narrow lanes
= if vehicles are not driving in the middle of their
lane
Warnings may be issued in error when driving
close to crash barriers or similar continuous lane borders. Always make sure that there is suPcient
distance to the side for other traPc or obstacles.
Warnings may be interrupted when driving along-
side long vehicles, for example trucks, for a pro- longed time.
Blind Spot Assist is not operational when reverse gear is engaged.
Blind Spot Assist and the exit warning are not
operational when a trailer is coupled to the vehi- cle and the electrical connection has been cor-rectly established.
The exit warning may be limited in the following situations:
= when the sensors are covered by adjacent
vehicles in narrow parking spaces
= when people approach the vehicle
= in the event of stationary or slowly moving
objectsFunction of brake application (Active Blind Spot
Assist)
If Active Blind Spot Assist detects a risk of a side impact in the monitoring range, a course-correct-ing brake application will be carried out. This is
designed to help you avoid a collision.
The course-correcting brake application is availa- ble in the speed range between approximately20 mph (30 km/h) and 125 mph (200 km/h).&WARNING Risk of accident despite brake
application of Active Blind Spot Assist
A course-correcting brake application cannot
always prevent a collision.
Always steer, brake or accelerate your- self, especially if Active Blind Spot Assist
warns you or makes a course-correcting
brake application.Always maintain a safe distance at the
sides.Driving and parking245

If a course-correcting brake application occurs,the red warning lamp will Oash in the outside mir-
ror and a warning tone will sound. In addition, dis-
play 1 indicating the danger of a side collision
will appear on the instrument display.
In rare cases, the system may make an inappro-
priate brake application. This brake application
may be interrupted at any time by steering slightly
in the opposite direction or accelerating.
System limits
Also note the system limitations of Active Blind Spot Assist; you may otherwise fail to recognizedangers (  page 244).
Either a course-correcting brake application
appropriate to the driving situation, or none at all,
will occur in the following situations:
= Vehicles or obstacles, e.g. crash barriers, are
located on both sides of your vehicle.
= An oncoming vehicle passes with little lateral
clearance.
= You have adopted a sporty driving style with
high cornering speeds.
= You brake or accelerate signiNcantly.
= A driving safety system intervenes, e.g. ESP n
or Active Brake Assist.
= ESP n
is deactivated.
= A loss of tire pressure or a defective tire is
detected.
= You are driving with a trailer and the electrical
connection to the trailer hitch has been cor-
rectly established.Activating/deactivating Blind Spot Assist or

Active Lane Keeping Assist
Function of Active Lane Keeping Assist
Active Lane Keeping Assist monitors the area in front of your vehicle by means of a multifunction
camera (  page 211). It serves to protect you
against unintentionally leaving your lane. You will
be warned by vibration pulses in the steering
wheel and guided back into your lane by a course- correcting brake application.
Active Lane Keeping Assist is available in the
speed range between 37 mph (60 km/h) and
124 mph (200 km/h).
Active Lane Keeping Assist can neither reduce the risk of an accident if you fail to adapt your driving
style nor override the laws of physics. It cannot
246Driving and parking

take into account road, weather or traPc condi-
tions. Active Lane Keeping Assist is only an aid. You are responsible for maintaining a safe dis-
tance, for vehicle speed, for braking in good time
and for staying in lane.
The status of Active Lane Keeping Assist is dis-
played in the on-board computer:
=

=When ESP n
is deactivated.
= When you are driving with a trailer and the
electrical connection to the trailer has been
correctly established.
= If a loss of tire pressure or a defective tire is
detected and displayed.
If you deactivate the Active Lane Keeping Assist
warning and the lane markings were not clearly
detected, it is possible that no lane-correcting brake application will take place (  page 248).
The system may be impaired or may not function
particularly in the following situations:
= If there is poor visibility, e.g. due to insuPcient
illumination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
= If there is glare, e.g. from oncoming traPc, the
sun or reOections.
= If there is dirt on the windshield in the vicinity
of the multifunction camera or if the camera is
fogged up, damaged or obscured.
= If there are no lane markings or several
unclear lane markings are present for one
lane, e.g. around roadworks.= If the lane markings are worn, dark or cov-
ered.
= If the distance to the vehicle in front is too
short and thus the lane markings cannot be detected.
= If the lane markings change quickly, e.g. lanes
branch oM, cross one another or merge.
= If the road is very narrow and winding.
= Vehicles with Driving Assistance Package: if
the radar sensors in the rear bumper are dirty
or covered in snow and an obstacle is detec-
ted in your lane, no lane-correcting brake
application takes place.
